A nmnn'neano imb o,ism; Serial no. 528,324. Qi'omodeif- To all whom it may concern:

be it known that 1, Laws HALLOCK Nash, acitizencpf the Unitedfitates, and a resident of South Nfwalh, in the county of Fairlield and State 0 :LConnecticnt, have invented certain new and useful Improvements in Water- Meters, of which the following is a specifica- My present invention consists, in general terms, in combining with the piston of a Water meter having an orbit motion a chamber having sph rical ends arranged so that gravity tends t drive the piston either away tremor. toward the center of the chamber, depending upon the curvature of such end waits. Watermeters having pistons operating with an orbit motion alone, or with other motionor motions, are now Well known in this art. For exam ple, in a patent granted to me January 21, 1879, No. 211,582, as Well as in snbsequentpatents, I have shown anddescribed a waterneher the piston of which has an orbit motiomto'gether with a motion of rotation around; its axis. Again, in a patent granted to me July 29, 1890, No. 433,088, and in other patents, I ha}; shown and described a meterthe piston 6% which has an orbit motion but no'motion of rotation around its axis. Again, in a patent granted to me June 17, 1884, No. 300,629, and in other patents, I have shown and described another meter the piston OflWhiGll has an orbit motion and an oscillating motion about its axis. Again, in a patent granted to one April 7, 1891, No. $49,821, I have shown and described another meter the piston of which tion of rotation around its axis and in other forms Without such rotation. These are some of the many meters which might be mentioned characterized by having a piston moving in an enumeration is regarded as unnecessary here. My present invention is applicable to all forms of meters characterized by such orbit motion of the piston, irrespective of the fact whether other motions are or are not present, and irrespective of the characterof the other motions present and of the details of construction of the devices.

I will describe my invention applied to three difierent forms of meters having pistons moving with an orbit motion as examanother form 0t" meter,

. ti1erdescription ples of th'e applicability of my invention te radicallydifferent structures.

Figure 1 is a horizontal section through form of metcr'on the line 11, Fig. 3'. Fig. 2 is a section through the same meter on the line 2 2, Fig. 3. FigJ-S is a vertical-I section, and,

Fig. 4 a top view, of the same meter,- the cap being removed. Big. 5 is a horizontal section through another form of meter. onfthe line 5 5, Fig. 6, and Fig. 6 is a verticaizasection through the same. Fig. 7 is a top viewfot (that shown iu Fig. 8,) the ca being removed; Fig 8 is a vertical sectio U through the-same. Fig. his a horizontal section through the same on the line 9 9, Fig.8 and Fig. 10 is a verticsilse'ction through the meter-chamber and the piston removed fromthe external case.

Referring to Fig. 1, 5 is the piston and 6 the measuring-chamber. .7 7 arethe passages leading from the valve to hers, through which water is admitted and discharged. These passages are curved arid at their inner ends are controlled by ports 8; and 9 of the piston. The pistonaud the,

chamber are provided with points, the points the cylinder-charm on the piston being less in number than the points on the chamber. This-piston, therefore, has a motion of rotation around its axis. As it always stands eccentrically with refer ence to its chamber and moves about constantly, maintaining this eccentric relation,

it has what l'term anorbitmotion. A farof this style of meteigwhich is known to the trade as the Crown and is described i' patents previously granted to me, among 0t ers, No. 211,582, dated January 21, 1879,.and No. 211,769, dated January 28, 1879, iscousidered unnecessary here.

' Referring to concentric position, and in doing so presses.

with points; but in this instance the points on the case and piston are of equal nurnhenend hence the piston, whileit has an orbit motion, does not rotate around its own axis. 20 is the piston and2l" the chamber. 61, 62, and 63 are the ports; As in the other case, the'pision is itsown valve, admitting the water to and from the'measnring-spsces. v A further description of'the structure and mode of operation of this device is deemed unnecessary here, in view of the fact;,th2.t meters constructed on this 'generel plan are known to the art is the Hersey T andnre described in patents already issnedas, for example, my IIatent'No. 433,088.

Referring to Fig. (5 it will be observed that in this case the chamber end walls are also spherical, but the curvature is in the opposite direction to that of the walls of the chamber shown in Fig. 3, so that here gravity constantly tends to cause the'center of the piston torecede from thocentcr of the case, or, in other words, to increase the eccentricity of the Thus gravity preserves or tends to preserve the joint-forming contact of the piston, as will be seen by reference to Fig. 5.

' Referring to Figs there is shown a piston 30 of circdlnrjorm, sense 3!, an abutment 32, and e rhriiitl nbntmcnt 42. The piston is slit. to straddle this abutment and is provided witnn'stmi'iiifworking in connection with a. roller 4.1,ettached to the case. The piston in this case also has an orbit motion whileit has semen ticn thereto. .A- further description of this form of meter is deemed unnecessary here, in View of the fact that it is well known to the trade as the Gem, end is described in petents already issued,among others my Patent No. 300,629. Y

Referring to Fig. 8 it will be seen that the ends of the chamber are curved, so that gravity constantly exerts a. force tending to press the piston in joint-forming contact with its C359.

The feature in common to allthe forms described is the orbitmotion of the pistons and the spherical ends of the measuring-chambers. I might describe still other forms of meters involving the same principle, as it is applicable to many forms; but those already described are deemed tobe sufficient to inforni those skilled in the art of the nature of my invention and to instruct them how it may be applied.

-Wha.t I claim, and desire to secure by Let tors Patent, is

an oscillating motion about its axis in addi- 1. in a water meter, the combination with chamber having spherical-,end-walls of a piston hnving spherical ends operetingtherein with an orbit motion.

2. In sweeter meter, the combination of a chamber having spherical end-wells of a' piss.- ton having spherical ends operating therein with anorbit motion and having also a. motion of rotation around its axis.
